Winstone Aggregates (Hunua) – GP550 Installation

About the Customer

Winstone Aggregates is a leader in aggregate products and services in New Zealand, operating eleven extractive quarries, two Joint Venture quarries with partners, four clean fills, six labs and a fleet of 80 bulk trucks. They are a trusted aggregates solution partner for the concrete, roading, rail, and other infrastructure industries.


Winstone Aggregates retired their existing Sandvik H6000 cone crusher and needed a modern replacement.


Winstone Aggregates chose the reliability of a Metso GP550 cone crusher as their replacement. Teamed with MIMICO’s service and parts support and MIMICO Engineering’s turnkey solution, including design and installation, the transition was a success.

Dealing with a tight installation timeline to minimise production disruption our 3D design capability helped alleviate any potential installation risks. The development of a custom fabricated sub-frame with rubber dampers and new vee-belt guarding helped to create the space for a successful installation.

Why was MIMICO chosen for the job?

MIMICO had the experience and expertise to complete the job to the expected levels. As the New Zealand distributor of Metso’s crushing and screening equipment, we were able to supply Winstone Aggregates with a world class cone crusher.
